The employers aren't obligated to employ anyone. What do you think happens to the "slave-wage class" when the job disappears entirely?
Are you claiming that wages in the restaurant industry are kept artificially low because of companies artificially capping salaries, and that politicians are enforcing it? If so, is there a source for this? AFAIK the pay is bad purely because of market reasons (ie. there are more people willing to do it than there are positions).
Federal minimum wage is $7.25 for tipped employees its $2.13
Lobbying groups contribute to keeping wages low: https://www.politicalresearch.org/2015/04/14/chain-restauran...
Herman Cain former presidential candidate and CEO of godfather's pizza specifically built his lobbying career on this.
Not claiming it, its a fact.
The "facts" in this comment are similar, but not the same as the claims made in your original comment. Specifically, it only presents evidence of businesses removing government restrictions on the minimum price of labor. It does not present evidence of businesses keeping wages "artificially low" (ie. below the natural market clearing price). If anything, removing the restrictions stops restaurant wages from being artificially high.
The closer analogy here would be if for whatever reason there was a law saying that "engineers" had to be paid $200k minimum, and tech companies lobbied for software engineers to be exempt. That's already very different than software companies suppressing wages (eg. by colluding with each other not to compete on wages). Another wrinkle to this is that tipped employees receive tips. If software engineers were receiving royalties in addition to their normal salaries, I would think it's fair for them to be paid lower minimum wage than other engineers that don't receive royalties.
And we're not obligated to provide them with people desperate enough to work their shit jobs either.
